Shift, I haven't gotten that far in Still Life yet--when you went back to a save, did you use the walkthrough to work your way forward again? That's about the only way to be sure you haven't missed some little detail in some of these picky games...

I got a little stuck here, too, in a silly way. When I was close to the crates the cursor showed I could move to them but I couldn't get Gus to move. Finally after about 10 tries I stumbled upon the fact that when you are zoomed out he will jump to them but not when you're close up. Crazy.

I found that the crates "look" like they are lined up next to the two stacked ones but really aren't. That was where I had problems till I figured out I needed to move them all the way to the right and then up one next to the two stacked crates (there are actually two spaces below the stacked crate but it isn't all that obvious). All along I thought I was right next to them and the view made me think I was correct but when I jumped over I still couldn't cut the chains. The perspective here is tricky but once I figured it out voila!
